Yes. That is the basic question. Not all X drivers need it and potentially the current kernel drm modules can use the PAT infrastructure that has been merged.
Further a SMM monitor running 100 times or more slower may cause problems if SMM mode is entered frequently, slowing down the entire system not just X.
So if you don't have X or you have a crazy SMM monitor this can be an issue.
